Design of CPW-Fed High Rejection Triple Band-Notch Uwb Antenna on Silicon Substrate With Diverse Wireless Applications

Abstract

Abstract-In this paper, a CPW-fed circular patch UWB-extended bandwidth antenna is proposed which is fabricated and characterized on silicon.The proposed antenna covers fractional bandwidth of 132.08% with high rejection triple band-notch characteristics [WiMAX(3.30 GHz-3.80 GHz)/WLAN(IEEE802.11a/h/j/n 5.15 GHz)/X-band downlink satellite communication system (7.25 GHz-7.75 GHz)]. Gain and efficiency of the proposed antenna in the entire bandwidth vary between 3.96 dBi-10.98 dBi and 84%-95%, respectively. Also, group delay in the entire operating band is ≤ 1.0 ns. Furthermore, the proposed antenna exhibits good dipole like radiation pattern in E-plane and omnidirectional pattern in H-plane with small dimension of 20 × 20 × 0.5 mm 3 .

A Very Compact Mimo Antenna With Triple Band-Notch Function for Portable Uwb Systems

“…The antenna is fabricated on a low-cost FR4 PCB substrate with relative permittivity (ε r ) of 4.4, loss-tangent of 0.02 and substrate thickness of 0.8 mm. The overall size of an antenna is 18×21×0.8 mm 3 which is very small compared to the antennas mentioned in [24][25][26][27][28]. The proposed antenna comprises two radiating elements which are horizontally placed on top of the substrate to save space.…”

“…This can also be done by adding strips or stubs adjacent to the radiator or ground or feed line as discussed in [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Each slot or strip can function as a resonator, and the slot or strip length controls the notch center frequency.…”

“…Overall size of the antenna is 18 × 21 × 0.8 mm 3 which is very small compared to the antennas reported in [24][25][26][27][28]. Two simple planar monopole elements are used as antenna elements of the UWB MIMO antenna, fed by a 50-Ω microstrip line.…”

SWB MIMO Antenna with Dual Band Rejection Characteristics and Polarization Diversity for UWB Applications

“…Also to suppress the interferences of the mentioned narrowband systems, different methods such as etching inverted L-shape [14], U-shape [15] and T-shape [16] slots of different dimensions on the ground plane, on the feed line and on the radiating patch have been proposed, respectively. Embedding different types of split-ring resonators on the radiating patch [17] and [18], placing various strips near the feed-line [19], or near the ground plane [20], utilizing parasitic elements such as bended dual L-shaped branches on the patch [21] and using substrate integrated waveguide (SIW) based metallic via integration of hexagonal and semi-hexagonal parasitic slot [22], have been utilized to obtain UWB antennas with single or several band-notched characteristics.…”

“…As reported, multiband including UWB, UWB lower and middle, with single dual band (lower and upper UWB) is obtained using PIN diodes in the slotted ground . Also notched band characteristics are obtained by etching slot or by inserting stub on different patch elements . Multiwireless applications such as ITS, WLAN, WiMAX, direct broadcasting satellite, and so on are designed with switchable coplanar linearly polarized multiband microstrip patch antenna and are fabricated .…”
